摘要翻译:
我们研究带电布朗粒子在外磁场中的运动。结果表明,在各向异性摩擦情况下,质点速度各分量之间存在相关关系,在定常极限处渐近为零。当磁场小于由摩擦各向异性决定的临界值时,关联的弛豫在时间上是非振荡的。然而,在较大的磁场中,这种弛豫会发生振荡。该现象与磁场和各向异性耗散同时影响引起的变换随机力分量的统计依赖性有关。

英文摘要:
We study the motion of charged Brownian particles in an external magnetic field. It is found that a correlation appears between the components of particle velocity in the case of anisotropic friction, approaching asymptotically zero in the stationary limit. If magnetic field is smaller compared to the critical value, determined by frictional anisotropy, the relaxation of the correlation is non-oscillating in time. However, in a larger magnetic field this relaxation becomes oscillating. The phenomenon is related to the statistical dependence of the components of transformed random force caused by the simultaneous influence of magnetic field and anisotropic dissipation.
